The minimum length of time from registration to revocation was a day and a
half.  

The median length of time from registration to revocation is 5 years, 225
days.

The mean length of time from registration to revocation is 6 years 192 days.

The maximum length of time from registration to revocation is 23 years 104
days (a legacy registration that came under RSA due to a transfer.)

The maximum length of time from registration to revocation for a non-legacy
block is 11 years, 187 days.

Hope this is helpful!
